The objective was to evaluate the performance of surveillance cultures at various body sites for Staphylococcus aureus colonization in pregnant women and newborns (NB) factors associated with nasal colonization. For NB, 4 were evaluated: nares, oropharynx, perineum, umbilical stump (birth, third day, weekly). women, during labor: anterior anus, oropharynx. Nasally colonized patients compared only extranasally. Colonization 53% 392 (methicillin-resistant S. [MRSA]: 4%) 47% 382 NB (MRSA: 9%). newborn patients, best site (methicillin-susceptible [MSSA]: 64%; MRSA: 68%) combination nares + (MSSA: 86%; 91%). Among 59%; 67%) oropharynx 83%; 80%). A smaller number household members MRSA carriage (2.2 ± 0.6 versus 3.6 1.8; P = 0.04). In conclusion, multiple culture are needed. Control programs based on may be compromised.
